"The TN802B MAP-D (Multi-Application Platform for DEFINITY) Media
Processor circuit pack
and the TN2302 Media Processor circuit pack provide the audio
bearer channels for H.323
voice over IP calls.
Å“ One TN802B circuit pack has one MEDPROPT media
processing resource; that one
TN802B MEDPROPT can handle 31 channels, for a total of 31 channels
per TN802B.
Note that the TN802B has 11 physical DSP devices but they are
treated as one logical
MEDPROPT by Communication Manager software.
If the list ip-codec-set screen specifies only G.711 mu-law or
G.711 a-law as the
audio codecs, the TN802B MEDPROPT can service 31 channels. If any
other codec type
(G.723-5.3K, G.723-6.3K, or G.729) is administered, the TN802B
MEDPROPT can service
22 channels.
Å“ One TN2302AP has 8 MEDPROPTs; each TN2302 MEDPROPT
has the processing
capacity to handle 8 G.711 coded channels, for a total of 64
channels per TN2302. Note
that early TN2302AP boards have eight physical DSP devices. Vintage
11 and later
TN2302AP boards have two physical DSP devices. Both board
configurations provide
eight MEDPROPTs and a total of 64 channels.
When only G.711 codecs are in use the TN2302AP has the processing
capacity to handle
64 channels. If only G.723/G.729 codecs are in use the TN2302AP has
the processing
capacity to support 32 channels. If a combination of G.711 and
G.723/G.729 codecs are in
use the number of channels supported will fall somewhere between 32
and 64. Use the
list ip-codec-set command to display the administered codecs.

So, if I'm understanding the above correctly, it would appear that
the TN2302 will support 64 DSP's (Talk Paths) at G.711MU or A due
to the fact that there is no compression or overhead algorythems
being applied. So, do you think that it would stand to reason that
the available DSP resourse pool decreases with the higher
compression due to overhead processing at the TN2302?
